Safety

Safety, built in.

Every machine in the range uses PEM/SPE membrane separation, so the user-facing stream is high-purity molecular hydrogen — never a flammable gas mixture. Multi-layer cut-offs handle the rest.

Separated gas streams

PEM/SPE separation produces hydrogen and oxygen in independent channels. The cannula delivers pure H₂ only — no flammable mixture at the user.

Multi-layer cut-offs

Automatic shut-down on over-temperature, over-pressure or low water level. The unit fails safe by default.

Clean water cycle

Distilled or deionised water in the internal reservoir. Simple top-up and full change schedule documented in the manual.

Studied at this dose

Published trials at the inhaled concentrations produced by consumer inhalers report no significant adverse effects.

When to consult a clinician first

Hydrogen Machines products are general wellness devices, not medical devices. Speak to a qualified clinician before starting hydrogen inhalation or hydrogen bathing if you are pregnant or breastfeeding, are under 18, have a serious cardiovascular, respiratory or neurological condition, use supplemental oxygen, are in active cancer treatment, or take medication where oxidative stress plays a defined clinical role.
